ATTACHMENT FOB. SAFETY RAZORS.

Application tiled June 9, 1922. Serial No. 567,119.

To all. whom t4 may concern:

Be it known that I, MILTON THAYER NEW- MAN, a citizen of the UnitedStates, residing at Miami, inthe county of Dade and State of Florida,have invented certain new and useful Improvements in Attachments forSafety Razors, of which the following is a specification. f.

Thls invention relates to razors, and the primary object of theinvention is to provide an attachment for safety razors which is soconstructed as to effectively holdv the blade against movement duringall adjustment of the razor, and to prevent the clogging up of the guardplate.

In use of safety razors of the character disclosed in U. S. LettersPatent 775,135 granted November 15, 1904, on the invention of King C.Gillette, hereinafter termed original Gillette type, difliculty isexperienced in shaving when theI razor is ad justed for giving a closeshave, due to the fact that the blade is loosened in the holder.

which permits movement or chattering of the blade, causing the cuttingof the skin of the user. In an improved razor disclosed in Patent#1,328,024, issued-J an. 13, 1920, on the invention of Edward R.Wharton, the guard late of the original Gillette type is modifie t0prevent clogging of the uard plate and to permit adjustment of the ladeto be had'without the loosening thereof in the holder. While this safetyrazor of thev new type accomplishes its purpose, the improvement cannotbe readily incorporated in the razor of the original Gillette type,

thus necessitating the buying of a complete new razor.

It is therefore another prime object of this invention to provide aninsert for connection with safety razors of the original Gillette typefor effectively spacing the l blade from the guard plate to. preventvclogging of the plate and to permit a wide range of ,adjustment oftheblade to be had relative to the ard plate without the loosening of the bade in the holder.

'A still further object of the invention is to provide an improvedattachment for safety razors of the above character, which will' bedurable and eicient in use, one that will be simple and easy tomanufacture,and one which can be readily associated with thesafet `razorin an expeditious manner.

With these and otherobjects in view, the

invention consists in the novel construction,-

arrangement and formation of parts, as will be hereinafter morespecifically described, clalmed and illustrated in the accompanyingdrawings, forming a, part of this specification, in which drawings: v

Figure 8 is a section taken on the line 8-8 of Figure 7, showing afurther modified form of the insert or attachment in plan.

While three forms of the improved atl tachment or'insert havebeenillustrated, it is to be understood that other forms may be made withoutdeparting from the spirit or scope of the invention.

The razor A is, as stated, of the ori inal Gillette type and includesthe elongate arcuate sha ed cap plate 1Q, which normally overlies t eelongated arcuate sha ed guard plate 11 with the concavity of t e formerconfronting the convexity of the latter. The cap p ate 10 supports theinwardly extending pins 1 2 for the shaving blade 13, and these pins areadapted; to extend through the bladev in the ordinary manner and throu hthe guard plate 11. l'Adjustment is h between the guardplate 11 and capplate-10 inthe ordinary manner, and the cap plate 10 cansupport theinwardly extending centrally disposed stud 14 on which can be threadedthe handle 15. Thus,'by turnin the handle, the blade 13 is adapted to beexed and held rigidl in place between the cap late and tie guard plate11. The guar plate has its .lateral edges provided, of course, with. theusual guard j teeth 16.

In all of the forms of the improved attachment or insert, the same isadapted to be placed between the ard plate 1'1 and the lade 13, asclearly s own 1n Figures 1 to 3 inclusive, 5 and 7. x

The improved insert or attachment B is preferably formed of flexiblespring matcrial, such as steel and consists of an elongated plate,having its ends curved, so as to conform to the general configuration ofa Gillette safety razor blade. llhis plate is adapted to extend at leastthe full length of the guard plate 11, and is of such a width that itslateral edges will lie inwardly of the guard teeth 16, as clearly shownin Figure 4 of the drawin s and linwardly of the longitudinal edges 0%the cap plate 10, as shown in Figures 1 and 2. This plate 17 is providedwith a pair f longitudinally extendi ing corrugations 1 on oppositesides of its longitudinal center with their convexities engaging theguard plate, and the longitudina or lateral edges of the plate arepreferably struck downwardly at an incline as indicated by the referencecharacter" 19. At the longitudinal center of the plate 17, suitableopenings 20 and 21 are provided respectively for the ide pins l2 for theblade 13 and the adjusting stud 14.

In use of the attachment, the blade 13 is placed on the pins in theordinary manner, after which the attachment B is placed on said pins andthe guard plate l1 is moved into engagement with the attachment. Thehandle 15 can now be adjusted in the usual way. The attachment willfirst assume a position as shown in Figurell of the drawings, holdingthe blade 13 into intimate engaglement ywith the longitudinal edges bounin the concavity of the cap plate 10. As t e handle 15 is adjusted, theattachment and blade will be flexed, as shown in Figure 2 of thedrawings, so as to` arcuate into the cavity of the cap plate, brmgmg5the cutting edges of the blade closer to the ard teeth 16. The handlecanbe adjuste until the plate 17-is' flexed to such a position that thesame assumes an arcuate configuration as shown in Figure 3 of thedrawings. This, of course, brings the. cutting ed es of the blade 13relatively close to the tee A16 lbut at the same time spaces the cuttingedges of the blade a suiiicient distance away from the guard teeth toprevent the clogging up thereof by the beard of the user. t

In the form C, the attachment consists of a rectangular shaped plate 25,which has `a.

length substantially equal to or more than the guard plate 11 and awidth less than the width of the cap plate and guardI plate so that thelongitudinal edges of the plate 25 will lie well inwardl o'f the guardteeth 16 formed on the guar plate 11. This plate 25 isl also formed ofresilient material and is preferably formed of a plurality of relativelthin laminations 26. At the longitudina center of the plate 25 isdsposed a pair of openings 27 fort-the blade guider ins 12 and a centralopening 28 for the a justing stud 14. This attachment is placed on therazor in the same manner as the form A and adjustment can be had in thesame manner. If it is found, however, tliatthe blade 13 cannot beadjusted close enough to the guard teeth 16, certain laminations can betorn oi' of the plate 25, thus reducing the same in thickness.

In Figures 7 and 8 of the drawings is illustrated the forni D of theattachment, which consists ot' the longitudinally extending spacedparallel'bars 30, connected by transverse strips 31, which may beprovided with openings 32 for the reception of the pins 12. The bars 30may be of circular shape 1n cross section, if so desired, and it canbesecn that these bars form fulcrum shoulders on which the blade can beflexed. This attachment also spaces the edges of the blades a suiicientldistance from the teeth 16 to prevent thc clogging u thereof -asheretobefore dcscribed. Adjustment of the blade 13 relative to the teeth16 can bc had by the turnin of the handle 15.

rom the foregoing description, it can be seen that an improvedattachment has been provided for razors of the original Gillette typewhich will effectively permit a Wide range of ad'ustment of the blade`relative to the guar plate Without the blade losing its rigidity orchattering within the holder, and which will effectively prevent therazor from clog ing up, thus eliminating the necessity of telling therazor apart to clean the same during a' shave.

Changes in details may be made without departing from the spirit orscope of this invention; but, p

I claim:

l1. The combinatior with a safety razor including a cap plate and aguard plate, the

cap plate having 4a concave face confronting the guard plate, means foradjusting the plates relative to one another, and a. flex-A ible blade'engaging said cap plate; of a.

- a flexible insert relatively narrower than the cap plate, disposedintermediate the guard plate and blade, and acting up n said blade' toarcuate the latter into the/concavity ofthe cap plate and intointermediate contact with the longitudinal edges of the cap platebounding said concavity.

4, The combination with a safety razor i including elongated cap andguard plates,

the plates having concave and convex faces, respectively, confrontingone another,

means for adjusting the plates relative to one another, and a flexibleblade engaging said cap plate; of a flexible insert relatively narrowerthan the cap plate, disposed intermediate the guard plate and blade, andacting upon said lblade`to arcuate the latter into the concavity of tliecap plate and into intimate Contact y withA ,the longitudinal edges ofthe cap ;plate bounding said concavity.

5. The combination vwith a safety razor Vincluding elongated cap andguard plates,

the plates having concave and convex faces, respectively,v confrontingone another, means foradjustmg the plates relative to one another, andan elongated' flexible blade relatively wider than said cap plate. but;relatively narrower than said guard plate disposed in engagement withsaid cap plate and provided with longitudinal cutting edges outwardly ofsaid cap plate; and an elongated {iexible plate, relatively narrowerthan said cap plate, disposed between said blade and guard' plate, andprovided with longitudinally extending corrugations spaced equidistantfrom the longitudlnal center of the iexible plate, the convex faces ofwhich engage the guard plate, whereby upon movement of the cap and guardplates toward each other, the flexible blade will be primarily Vflexedinto the concavity of the cap plate by engagement with the longitudinalportions of the flexible plate with the flexible blade adjacent thelongitudinal edges of the Cap plate, and upon further movement of thecap and guard plates, the central longitudinal portion of the flexibleplate will engage the central longitudinal portion of the blade and aidin arcuat-ing the blade into the concavity of the cap plate.

6. The combination with a safety razor including elongated cap and guardplates, the plates having concave and convex faces, respectively,confronting one another, means for adjusting the plates relative to oneanother, and an elongated flexible blade relatively wider than said capplate but rela.- tively narrower than said guard plate, disedgesoutwardly of said cap plate; of an insert initially engaging the blade'at its face opposite to said cap plate and slightly inwardly of thelongitudinal edges of the cap late at spaced apart lines to arcuate theb ade into the concavity of the cap plate and into firm engagement withthe longitudinal edges oft e cap plate bounding said concavity, when thecap and guard plates are moved toward each other.
